Having the two films together will make it a darker film[film?:film cutting machine], which is better for burning screens, because you want the design on the film as dark as possible to block the UV light. I’ve heard of people simply running the printed film through their printer again and it lines up correctly and gets a second layer of ink, which I can’t advocate but you are free to try. When I started out, I’d go to Kinko’s and get two films printed of each design, and tape them together. It worked but going to Kinko’s was a hassle, so I got the laser printer so I could just print[print?:printing image graphic cutting solution] out films at home. This was back when I worked in a laundry room with a very bare bones operation.
Be sure to get the correct films for either inkjet or laser printers. I used to buy laser film, also known as vellum, from Ryan Screen Supply. If you’re printing[printing?:printing cutting finishing solution] for profit, make sure your screen set up charge covers the cost of your film, as well as toner/ink and emulsion as well as reclaiming chemicals. I only charge $10 to set up a screen, which is low for the industry. Sometimes with large and/or highly-profitable jobs I waive the screen set up charges.
If you are using a laser printer, there is an easy way to make your films darker after you print them out. There is a product called Casey’s Ultra Black, which is a spray toner enhancer. “Blacker blacks in a can.” I used to buy it from Ryan Screen Supply but I can’t find it on their site now. You simply spray it on your film and then let it dry and the design gets darker. Be careful not to spray too much, and make sure your films are laying completely flat, or sometimes it will make the toner run.
